Tilt/Trim Troble

[wilson973]

I have replaced the tilt motor on my 70 hp Johnson and replaced both Relays. I still cant get the motor to move unless I put the 2 wires straight to the battery. If I press the up or down button on the control box I get 12.87 volts between both leads. I have checked all wires. None burnt or cut. Was working one day the next day nothing. Any ideas?

Here's a link for the wiring diagram:

Trace the black ground wires from the relays through to the engine block and make sure that all of the connections are clean and solid.

Note that green may appear yellow in the diagram.

Push the up button and check voltage at blu/wht wire on relay post #86. Do same with down button and other relay grn/wht wire. If both voltage check out then you have good control and the only thing left is bad ground. well, almost only thing. I remember reading that some engines have intermittent problems caused by a loose wire at trim limit switch ... but I can't remember if it was Evinrude or Mercury .... hmm ... does you boat have trim limit switch? maybe check that too if you have one.
